Fixed:
MACHINE = "qemux86-64"
require conf/multilib.conf
MULTILIBS = "multilib:lib32"
DEFAULTTUNE_virtclass-multilib-lib32 = "x86"
PREFERRED_VERSION_lttng-modules = "2.10.10+git%"
$ bitbake world
NOTE: preferred version 2.10.10+git% of lttng-modules not available (for item lib32-lttng-modules)
NOTE: versions of lttng-modules available: 2.10.10
ERROR: Multiple versions of lttng-modules are due to be built (/path/to/lttng-modules_2.10.10.bb virtual:devupstream:target:/path/to/lttng-modules_2.10.10.bb). Only one version of a given PN should be built in any given build. You likely need to set PREFERRED_VERSION_lttng-modules to select the correct version or don't depend on multiple versions.
This is because 2.10.10+git% will be built for non-multilib lttng-modules since
the PREFERRED_VERSION is set, but this version doesn't provide
lib32-lttng-modules, so 2.10.10 will be built, then the error happens.
Bitbake can't extend an extended recipe, for example:
virtual:multilib:lib32:virtual:devupstream:target
Or in a reverse order:
virtual:devupstream:target:virtual:multilib:lib32
So disable devupstream when multilib is enabled.

This class lets you use BBCLASSEXTEND to add a variant of the recipe that
fetches from an alternative URI (such as git:) instead of a tarball.
For example:
BBCLASSEXTEND = "devupstream:target"
SRC_URI_class-devupstream = "git://git.example.com/example"
SRCREV_class-devupstream = "abcd1234"
This variant will have DEFAULT_PREFERENCE set to -1 so it needs to be selected
to be used, and any development-specific tweaks can be done with the
class-devupstream override, for example:
DEPENDS_append_class-devupstream = " gperf-native"
do_configure_prepend_class-devupstream() {
touch ${S}/README
}
It currently only supports creating a development variant of the target recipe,
not native or nativesdk. The BBCLASSEXTEND syntax (devupstream:target) was
chosen so that support for native and nativesdk can be added at a later date.
Support for other version control systems such as subversion is limited, as
bitbake's automatic fetch dependencies on for example subversion-native are not
generated.
